Clinical trials

The European Union Clinical Trials Register   allows you to search for protocol and results information on:
  • interventional clinical trials that were approved in the European Union (EU)/European Economic Area (EEA) under the Clinical Trials Directive 2001/20/EC
  • clinical trials conducted outside the EU/EEA that are linked to European paediatric-medicine development

  • EU/EEA interventional clinical trials approved under or transitioned to the Clinical Trial Regulation 536/2014 are publicly accessible through the
    Clinical Trials Information System (CTIS).


    The EU Clinical Trials Register currently displays   43871   clinical trials with a EudraCT protocol, of which   7290   are clinical trials conducted with subjects less than 18 years old.   The register also displays information on   18700   older paediatric trials (in scope of Article 45 of the Paediatric Regulation (EC) No 1901/2006).

    Phase 1 trials conducted solely on adults and that are not part of an agreed paediatric investigation plan (PIP) are not publicly available (see Frequently Asked Questions ).  
     
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    E.2.3Trial contains a sub-study Yes
    E.2.3.1Full title, date and version of each sub-study and their related objectives

    Other types of substudies
    Specify title, date and version of each substudy with relative objectives: Select sites will participate in a musculoskeletal sub-study to undergo musculoskeletal imaging assessments at the time points indicated in Section 3.3. A
    musculoskeletal MRI will be performed to evaluate the structure and function of skeletal muscles as well as lean body mass.

    A subset of subjects will have a muscle biopsy performed at Week 12. The biopsy will be of the biceps muscle, preferably on the left arm. If the biceps muscle is not viable, prior approval from the Sponsor is required for using an alternate muscle of the upper extremity.

    Altre tipologie di sottostudi
    specificare il titolo, la data e la versione di ogni sottostudio con i relativi obiettivi: I siti selezionati parteciperanno a un sotto-studio di indagine muscoloscheletrica per sottoporsi a valutazioni di imaging muscolo-scheletrico con tempistiche indicate nella sezione 3.3. Una risonanza magnetica muscolo-scheletrica sarà eseguita per valutare la struttura e la funzione dei muscoli scheletrici così come la massa magra del corpo.

    Un sottogruppo di soggetti si sottoporrà a prelievo di biopsia muscolare eseguita alla settimana 12. La biopsia sarà del muscolo bicipite, preferibilmente sul braccio sinistro. Se il muscolo bicipite non è vitale, è necessaria l'approvazione preventiva da parte dello sponsor per l'utilizzo di un muscolo alternativo degli arti superiori.
    E.3Principal inclusion criteria
    A subject must meet the following criteria to be eligible to participate in this study:

    4. Able to cooperate with motor assessment testing.

    5. Has been on a stable dose of oral corticosteroids for at least 12 weeks before Screening and the dose is expected to remain constant (except for modifications to accommodate changes in weight) throughout the study. Note that no use of corticosteroids is considered a stable dose (ie, 0 mg).

    7. Subjects who are sexually active must agree to use, for the entire duration of the study, a condom and the female sexual partner must also use a medically acceptable form of birth control (eg, oral contraceptive).
    Refer to Appendix 1 for guidance on highly effective contraceptive methods.
